Door access control systems are digital security systems that ensure authorized access to your building. They ensure only authorized personnel are entering your building while keeping unauthorized personnel out. This can be extremely efficient in avoiding trespassing, vandalism, and other criminal activity at your business. Plus, because they are digital, they are more efficient in doing so than traditional lock-and-key systems. At the same time, door access control systems simplify entry to your building. Employees and other personnel no longer have to carry keys or unlock doors the old-fashioned way. You can issue users convenient forms of entry like smart card, tag, facerecognition, fingerprint and more.
